I wouldnt do a mohair blazer a duppioni silk one would be very stylish. Umm, err, I wonder if Scabal or Dormeuil dont carry something like this, give em a call. They may not sell toy uo directly but theyll check for you. Holland and Sherry do a very nice navy duppioni in their formal book, too dark for your needs but still very nice.

You might want to wait for Harrison's Sunbeam which wont look a thing like silk but will be a great summer blazer fabric.

Scabal sent me their dupioni samples, and the only blue was a navy. I'll keep an eye out for the Sunbeam. Thanks.

When RLPL was created, it was a big Ralph Lauren FU to the Italian RTW houses, particularly Armani. (Tom Ford is attempting to do the same now at a much lower level of impact.) The looks from the first few years, executed for him by the defunct Chester Barrie, borrowed heavily from 1930s Apparel Arts and, imho, Blades of Savile Row. Shoulders were often heavily padded and extended. There was often a slight bit of drape to the chest. Waists were nipped. Trousers were full. And in the first few years, RL seemed to spare no expense in the fabrics. RLPL reinvigorated RL as a RTW brand that could make some claims on a luxury product, an area in which RL had previously be faltering.

What we see today, of course, is heavily Italianized RLPL, with much of that unabashed Anglo-American design verve stunted. I sometimes read comments that Anglo-American style is sober and Italian more exuberant...but I think that the reverse was true for most of the past.
